Unbalanced nutrition as well as diseases of infectious and non-infectious etiology lead to a decrease in production and a significant loss of farm animals and birds. To mitigate these problems, various probiotic drugs (probiotics) are introduced into the diets of birds and animals for preventive purposes. The aim of the research was to study the effect of the Vitafort probiotic, containing antagonistic bacteria of the endophytic strain Bacillus subtilis B11, on the body of broiler chickens. The effect of Vitafort was assessed by measuring the live weight and average daily growth of birds. In addition, a morphological study of blood was carried out and the content of Bacillus subtilis in the small intestine was determined. It was found that the endophytic strain Bacillus subtilis B11 improved the intestinal microflora. Thus, on day 5 of its use, the number of microorganisms varied from 4.1 × 104 to 8.2 × 104 CFU/g, and on day 42 the same number varied from 4 × 108 to 5.8 × 108 CFU/g on day 42, the contents of red blood cells, haemoglobin, and white blood cells in the blood of chickens from the experimental group were higher by 6.44%, 3.44%, and 2.11%, respectively, than they were in the control group. Considering the above facts, it can be assumed that the absorption of nutrients in the intestine improved, and metabolic processes were activated due to an increase in the transport abilities of red blood cells.

Background and Aim: In recent decades, the use of various feed supplements is the current trend in poultry farming, among which phytogenics serve as alternatives to feed antibiotics. This study aimed to examine the effect of feeding various doses of milk thistle extract (Silybum marianum) on the morphological and biochemical parameters of the blood in broiler chickens. Materials and Methods: Experiments were carried out in an industrial poultry farm on broiler chickens of the Hubbard ISA F15 cross for 40 days. One control group and five experimental groups of day-old chickens were formed. The number of birds in each group was 50. Broilers of all groups received complete feed, and the experimental groups received an additional milk thistle extract at doses of 0.1, 0.5, 1.0, 1.5, and 2.0 mg/kg of body weight. Milk thistle medicinal plant extract was obtained using water-ethanol extraction followed by low-temperature vacuum drying. For the assessment of blood analyses, samples were collected from the wing vein of six chickens per group. Using unified methods recommended by the International Federation of Clinical Chemistry, the content of red blood cells, hemoglobin, white blood cells, total protein, protein fractions, triglycerides, glucose, calcium, phosphorus, and the concentration of alanine aminotransferase and aspartate aminotransferase in the blood serum were determined. Results: It was found that the introduction of milk thistle extract into the diet of broiler chickens with the aforementioned doses increased the number of red blood cells, hemoglobin, white blood cells in the blood, as well as a decrease in the level of albumin and an increase in the content of γ-globulins in its serum. Conclusion: The authors assume that the introduction of milk thistle extract into a complete feed for broiler chickens increased the anabolic processes in their bodies, accompanied by increased use of proteins of the albumin fraction as the main material for organogenesis.

Effect Of Water

The use of water with a modified isotopic composition in the diet of humans and animals, for example, with a reduced deuterium content, affects the rate of biological processes. In this regard, the targeted formation of the isotopic D / H gradient in the body can be used to increase its adaptive properties to external influences. Primates have a high anatomical and physiological similarity with humans, therefore, are an indispensable model for reproducing various pathological and toxic conditions in humans. The aim of the study was to study the effect of water with a low deuterium content on the hematological and biochemical blood parameters of rhesus monkeys and on the digestibility of nutrients of the diet. In the control group, primates consumed water with a natural regional content of deuterium equal to 150 mg / l, and in the experimental group - with reduced to 50 mg/l. The duration of the experiment was 35 days. The material for the study was venous blood, serum and feces of primates. Blood was drawn from monkeys before the use of deuterium depleted water and after the completion of the experiment. All blood samples (2.5-3.0 ml) were taken from the cubital or femoral veins of animals on an empty stomach and stabilized with a heparin solution. Laboratory studies of animal blood were performed on an automatic hematological analyzer (Beckman Coulter, USA) of the CoulterAcT 5diffCP brand. In order to study the effect of water with a reduced deuterium content on hematological parameters, we determined the number of red blood cells, white blood cells, platelets, hemoglobin concentration, hematocrit, the average volume of red blood cells, red blood cell anisocytosis, and erythrocyte sedimentation rate (ESR). The metabolism trial was divided into two periods. Preliminary - to exclude the influence of previous feeding and accustoming primates to cage conditions of keeping. Experimental - conducting a thorough accounting of consumed feed, excreted excrement. Feces were collected daily at the same time (morning and evening), weighed and ground in a mortar. At each collection, 50% of the homogenized mass was taken for analysis. The collected portions were stored in the refrigerator. After the end of the experimental (accounting) period in the collected feces, the initial moisture was determined by drying at 60-70 ℃ to constant weight. The resulting air-dry mass was thoroughly ground and analyzed. It has been found that the introduction of water with a reduced deuterium content into the diet of primates has a positive effect on feed conversion rate and blood biochemical parameters.

Aim. To study the feasibility of using feed additives containing powdered feed preparations with different lactulose content in the amount of 5 g/kg of extruded compound feed together with the main diet in terms of the effect on the quality indicators of raw materials and the natural resistance of the body of experimental rabbits. Materials and Methods. The effectiveness was evaluated after the control slaughter at the age of 150 days in the number of 5 heads from each group. The change in live weight was determined when the rabbits reached the age of 75, 105, 135 and 150 days by weighing on an electronic scale. The physiological state and resistance of rabbits were evaluated by hematological parameters. The obtained materials were processed by the methods of variation statistics. Results. The analysis of dynamics of changes of alive weight of animals showed that feed supplementation with lactulose had a positive impact on the growth of animals the live weight of rabbits in groups I and II were greater at 3.8 and 6.2% absolute increase in live weight during the period of experience increased by 5.3 and 7.9%, respectively, compared to control. At the same time, the effect of supplements on blood parameters should also be noted. In our studies, the rabbits of the experimental groups had an advantage over the rabbits of the control group in terms of the level of red blood cells by 0.94·1012 g/l (18.7%) and 1.12·1012 g/l; white blood cells - by 0.50·109 (7.2%) g/l and 0.59·109 g/l (8.5%), respectively. The level of hemoglobin in the blood of rabbits increased by the end of the experiment in the control group by 3.7%, in I – by 12.5%, in II – by 15.9%. Conclusion. Based on the presented results, it can be concluded that the data on quantitative changes in blood were due to the influence of feed additives, which contributed to an increase in the natural resistance of rabbits, and the best indicators were achieved by rabbits of the II experimental group.

The object of research is the components of feed additives, namely dihydroquercetin, blue-green algae spirulina and organic iodine, in various combinations used in feeding piglets from the first days of feeding and before transferring them to fattening, at the age of 90 days. Three groups of piglets, one control and two experimental ones, were formed according to the principle of analogues. Piglets of the first experimental group received to the general diet, a feed additive MKBA-1, consisting of Spirulina – 1 mg, dihydroquercetin – 3 mg, organic iodine – 1,5 mg per 1,5 kg of live weight per day; piglets of the second experimental group to the main diet received a feed supplement ICBA-1, consisting of Spirulina – 2 mg and dihydroquercetin – 2 mg per 3 kg of live weight per day. The use of dihydroquercetin, blue-green algae spirulina and organic iodine in various combinations in feeding piglets contributed to an increase in the adaptive ability of the body, pathogenetic reactivity and correction of metabolic processes, which provided a higher realization of the genetic potential of pigs. The introduction of feed additives into the diet of pigs contributed to an increase in the bactericidal activity of blood serum in the first experimental group by 1%, in the second experimental group by 14,1%, compared with the control group. The number of white blood cells in piglets of the experimental groups was lower and red blood cells is higher compared to piglets in the control group, which was reflected in the hemoglobin content of blood, which was higher than piglets from the control group by 2% and 8,9%, respectively.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

Selenium plays an important role for maintaining complex and adequate nutrition of fattened young pigs. It also has a big biological importance to maintain growth and health, as well as for biochemical and physiological processes This study presents the results of a production experiment to determine the effect of organic and inorganic forms of selenium on growth indicators, immunohematological blood parameters and slaughter qualities of fattened pigs in period I and II. Test feeding with various forms of selenium has been implemented with two groups of analogs (N = 60; n = 30), taking into account age and live weight. The experiment was conducted on castrates of large white breed, which were divided into two groups of 30 heads each following the principle of analogues (taking into account their age, live weight). The studied fattened pigs received standard complete feeds of the SK-5 and SK-6 types for a period of 105 days. Growing pigs were fed with organic selenium for 20 mg/kg as part of the feed 64 mixture per head in the first and second period of fattening, while the animals of the control group were fed with 0.3 mg/kg of the inorganic form of selenium. Including a chelated form of selenium in the complete feed of castrates at the rate established in the course of scientific and economic studies has led to 757 g of average daily gain, which is 8.1% more as compared to the control group. The concentration of red blood cells in the blood of growing pigs fed with 20 mg/kg of selenium chelate increased by 6.3%, hemoglobin – by 2.4%, and white blood cells – by 7.1% as compared to the control. Feeding organic selenium to fattened young pigs contributed to a significant increase in specific units of protein activity by 38.65% (p < 0.01), BASC – by 7.63%, as well as lysis – by 40.06% (p < 0.05), and phagocytic activity by 3.33% in blood serum as compared to the control. The half-carcasses of hogs who had received fed rations including selenium chelate fetured slaughter weight and slaughter yield, respectively, higher – by 6.4 and 0.6% as compared with the control analogues. The use of the established norm of organic selenium in the diets of fattened young pigs according to the results of production testing is economically profitable and contributes to a per-head profit of 420 rubles.
